FJytia as long as prcthorax but considerably wider, the 

 humeral cornei's strongly prominent, laterally nearly parallel, 

 in the apical third rounded and constricted, at the tips 

 broadly emarginate, fairly convex, near the suture slightly 

 impressed, at the base densely covered by silvery hairs, 

 roughly punctured, punctures rarely confluent. 



Abdomen considerably more narrow than elytra in posterior 

 parts but broader than prothorax, not tapering towards the 

 end, the three basal segments fairly strongly constricted 

 without lateral margin, last segment provided with a pair of 

 short and sharp chiti)ious hooks, shorter and not so strongly 

 curved as in St. hispinns Motsch ; basal segment densety 

 covered with whitish, stiflF hairs, which are parallel except 

 at the tips, where they are curved inwards. 



Punctures rough only at the constricted parts of the 

 segments, otherwise fine and not very deep ; the fifth ring 

 shows a free skinfold ; apical segment with a hairy spot 

 near its posterior margin. 



J-egs strong and of moderate length, femora fairly strongly 

 '•onstricted towards the tips, knees broadly infnscate. on the 

 feinora to more than the apical half, on the tibia not ouite 

 to the middle; on the femora the dark is strictly limited, 

 which'is not the case on the tibia; tarsi short, the first ioint 

 twice as lonii as the second. whi<^h is of the same length as 

 the following, fourth joint with broad appendices. 



Anterior parts of body only finely reticulated at the base of 

 elytra; abdomen deeply shagreened. 



The characteristics of the male-sex consist in a fairly broad 

 ;ind deep excision on the sixth ventral segment, which is 

 rounded at the base.

Typus in coll. Benick. 



Differs at the first glance from all other members of the 

 bisfinus group by the colouration of the knees ; no other 

 species shows a siniilar arrangement of hairs on the basal 

 parts of abdomen. It is possible that the dark colouration 

 of the 7th to 8th joints of the antennae is to be regarded 

 as abnormal.
